Let’s look at how to play a D2 (D Second) chord on the piano. We’ll also learn the pattern for building any second chord.
What Are Second Chords?
To convert the major chord into a second chord, we’ll add the second note of the matching major scale to the chord.
How to Play a D2 Chord
Then we’ll add the second note of the same scale to the chord: E.
So to play a D2 chord on the piano, we’ll play:
D – E – F♯ – A
You may have also heard of “add9” chords. A Dadd9 chord is a D major chord with an added major ninth (the ninth note of the scale). Since major scales only have eight notes, a major ninth is actually the same note as the second note of the scale, just one octave up.
So the notes of a Dadd9 and D2 chord are the same, just in a different order:
Dadd9: D – F♯ – A – E
D2: D – E – F♯ – A
Other Chord Types
There are many other chord types you can learn. Here are some others:
Now you know how to play a D2 chord on the piano, and you can use that knowledge to build any second chord.
Using patterns to build chords is a lot of fun. Once you know the pattern for how to build a particular type of chord, you can use that pattern starting on any note!
